Part of the reason for the recent crash in cryptocurrency markets was CoinMarketCap.com’s decision to exclude South Korean exchanges from its listings. The website, which is also among the most-visited sites in the world, is regularly consulted by investors for the latest prices. It has largely shunned the spotlight, preferring to let its data do the talking.
On the day that the crash occurred, however, the silence proved catastrophic for cryptocurrency investors. Even as hundreds of billions of dollars in value was wiped out from cryptocurrency markets, there was not much comment forthcoming from the site.
A WSJ article published this week provides additional details regarding the founder’s thought processes during that period. CoinMarketCap.com is maintained and operated by 31-year-old programmer Brandon Chez from an office in the Long Island City neighborhood of Queens, New York.
According to the WSJ article, Chez began excluding South Korean exchanges from his site’s calculations sometime on the evening of January 7, 2018. The following morning, on January 8, the site posted an update on its Twitter account outlining the reason for the exclusion ("extreme divergence" in prices).
By then, “a lot of users were complaining about the inaccurate prices,” Chez told the Journal, adding that he hadn’t realized the impact of his decision earlier. “I think the market was already on a downturn at that point so the timing was quite unfortunate,” he stated in an email.

To be sure, the incident hasn’t affected CoinMarketCap’s popularity. It still remains the most popular and comprehensive site for checking on cryptocurrency prices. Unlike individual exchanges, which often have large disparities in coin prices, CoinMarketCap.com calculates a volume-weighted average for cryptocurrency prices. It thus provides a snapshot of the currency’s valuation across multiple markets at the same time, making it easy for traders to evaluate their prospects.
While CoinDesk offers a similar service to traders, it does not have the breadth in cryptocurrencies and simplicity of interface that characterizes CoinMarketCap's presentation.
That said, competition may be on the horizon. The price disparities between individual coins provide an arbitrage opportunity for savvy traders. It is this demographic that Intercontinental Exchange Inc. (ICE), which owns the New York Stock Exchange, is targeting with its feed product announced recently.
